Damn! got the M-21 Gen 4 in today, FFL Guy installed the new extended mag release for me right there at the shop, he sold me a Blawkhawk Serpa holster too, hurried home, grabbed a pile of ammo and went to the bench, happy to report this pistol shoots to the sights with the 230 gr Gold Dot load at 963 fps, the 230 gr fmj-fp's at 950 also land with the gold dots in a snuff can sized group at a braced 20 yards.
Also damn glad to report all four 13 round mags are drop free, I heated her up pretty good running four full mags through it right quick, ran like a sewing machine, she's wiped off and on a cool down, jacking with the trigger dry firing it now, will take time to get used to that.
Overall very happy with fit, function and accuracy so far.
